_Dedicated Technology strives to make the highest quality after-market upper receivers possible by offering a wide variety of options to customize your weapon to your exact liking. Drawing from decades of experience, owner-operator Mike Milli produces and continues to develop new product lines; most recently the DTI Line AR. Workmanship, attention to detail, and friendly customer service are what Mike's customers have grown accustomed to and what you can expect from Dtech!

The basic custom upper conversion features a Shilen match stainless barrel with my ventilated, three-piece hand-guard. It also features my new, clamp-on, low-profile gas-block, and flat-top upper receiver with forward assist. Each upper comes complete with bolt/carrier, charging handle and magazine. These uppers can be used with any, un-modified, mil-spec lower receiver. You can switch from .223 Rem. to .25 WSSM in 20 seconds! I am now using the Magpul anti-tilt followers as a standard feature in all of my WSSM magazines. By using these followers, I have increased the reliable capacity of the magazine and enhanced the reliability of the upper.

_The DTI Line ARBack in the summer of 2009, one of my customers from Iowa asked me about a 6 mm cartridge that would be somewhere between the 6 x 45 and the .243 WSSM. He already had a .223 Remington upper, as well as a .243 WSSM upper, but just wanted something a little less expensive to shoot than the WSSM, and something with more horsepower than the .223. ...more on the DTI

_Dtech Float TubeNew for 2011, my new free-float tube is finally
finished. Over the last 18 years of working with, and building uppers, I
have gotten increasingly disappointed with the commercially available
float-tubes on the market. Most are of the two-piece design that forces
you to accept whatever torque you end up with when the barrel-nut is correctly
timed-up to the receiver. My new float-tube has a two-piece barrel-nut
that allows you to get perfect alignment for the gas-tube, without respect to
torque. This also allows you to have the vents and sling-stud always
time-up perfectly. The float-tube can be installed. removed and
reinstalled as many times as you wish, and you will never have to worry about
your sling-stud ending up anywhere but bottom-dead-center!
